I'm getting a reading of around 550 psi at idle engine warmed up. And drive normal its around 1200 psi. I was wonder if this is normal.

 

I should also add I had 3 no starts in the last 3 months from the cold temps. Its a 2004 F250 6.0.

 

Noraml. You need 500 psi to start.

 

that seems like a low idle psi.... I thought it was 580 for warmed up engine idle ICP reading.... could that number being 30psi low be an indicator of a leak somewhere in the Hpo system?

I know when my truck is fully warmed up it idles at 580 psi.

 

It is 580 at idle. I should have waited til I was able to check the values when I wasn't driving. I'm gonna check it with WOT after I drop my gram off
